Troubleshooting data caching

If you set the data cache of dashboards to auto-generate, in some cases, your browser window may stop functioning.

This issue is caused by a missing entry in six files that are located in installation_location\cgi-bin\templates.

Solution

To resolve this issue, edit these files:

  • cognos_apache22_loadbalance.conf
  • cognos_apache22_loadbalance_SSO.conf
  • cognos_apache24_loadbalance.conf
  • cognos_apache24_loadbalance_SSO.conf
  • cognos_IHS9.conf
  • cognos_IHS9_SSO.conf

For each of the above files, follow these steps:

  1. Go to installation_location\cgi-bin\templates.
  2. Open the file in a text editor.
  3. Add the following lines:
    <IfModule mime_module>
    AddType application/wasm wasm .wasm
</IfModule>
  4. Save the file.

When you have updated all six of the files, restart the Cognos Analytics service.
